Fault Condition: Code PID 240 with an FMI 7 (Mechanical System Not Responding/Out Of Adjustment) or 11 (Root Cause Not Known) will set if the Engine Management System (EMS) Module detects a software failure Code will set if the Engine Management System (EMS) Module detects a software failure, if the software is not production software, if either the truck is or has been involved in an engineering test, or if someone has attempted to program the Engine Management System (EMS) Module in an unauthorized manner. If this code occurs call MACK Reliability Engineering. Volvo All Engines (2004 Emissions) Fault Code:...

Fault Condition: The Total Vehicle Distance code will set when the Engine Management System (EMS) Module has lost the Vehicle Speed Signal from the Vehicle Electronic Control Unit (VECU). Possible repairs: 1) Verify that code PID 245 is set. If code PID 245 is not set, wiggle the harness and connectors to try to set the code. Visually inspect the VECU connectors and wires for poor connections.2) Is code MID 144, PID 84, PID 91, or PID 72 set?If code(s) MID 144, PID 84, PID 91, or PID 72 is set, repair code(s) MID 144: PID 84, PID 91, or...

Fault Condition: The Time Data Failure code will set when the Engine Management System (EMS) Module has lost the time stamps that are sent from the Instrument Cluster Module (ICM). The time stamps will be substituted by the Engine Management System (EMS) Module. Possible repairs: Turn the ignition key OFF first. 1) Verify that code PID 251 is set. If code PID 251 is not set, wiggle the harness and connectors to try to set the code. Visually inspect the ABS connectors and wires for poor connections.2) Connect a diagnostic computer. Turn the ignition key ON. Use the diagnostic computer...

Fault Condition: The Date Data Failure code will set when the Engine Management System (EMS) Module has lost the date stamps that are sent from the Instrument Cluster Module (ICM). The date stamps will be substituted by the Engine Management System (EMS) Module. Possible repairs: Turn the ignition key OFF first. 1) Connect a diagnostic computer. Turn the ignition key ON. Use the diagnostic computer to attempt to communicate with the Instrument Cluster Module (ICM). If communication can be made with the Instrument Cluster Module (ICM), the fault may be intermittent, wiggle the harness and connectors to try to set...

Volvo All Engines (2004 Emissions) Fault Code: PID 26 FMI 3 Fan Speed Fault Condition: The FMI of 3 (Voltage High) will be displayed for all code faults that result from the fan speed being less than 20 rpm.High engine coolant temperature could occur and cause engine shutdown. If fault code PID 26 is set with FMI 3, fault code SID 211 may also be set. Possible repairs: Turn the ignition key OFF first. 1) Disconnect EMS Module connector A. Disconnect the electronic fan drive harness connector. Check for continuity between electronic fan drive harness connector pin 5 and a...
